[Bug 1046543] Re: Touchpad stopped working EV=b in devices
Zaur Molotnikov, as per http://us.acer.com/ac/en/US/content/drivers an
update is available for your BIOS (1.08). If you update to this, does it
change anything?
If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
Thank you for your understanding.
